Neutron crystallographic structure of the reduced form perdeuterated Pyrococcus furiosus rubredoxin to 1.38 Angstoms resolution.

Template:ABSTRACT PUBMED 23225503

Function

[RUBR_PYRFU] Rubredoxin is a small nonheme, iron protein lacking acid-labile sulfide. Its single Fe, chelated to 4 Cys, functions as an electron acceptor and may also stabilize the conformation of the molecule.

About this Structure

4ar4 is a 1 chain structure with sequence from Pyrococcus furiosus. Full crystallographic information is available from OCA.
